Package io.micronaut.inject

Interface ExecutionHandle<T,R>

Type Parameters:

T - The target type

R - The result type

All Superinterfaces:

AnnotationMetadata, AnnotationMetadataDelegate, AnnotationMetadataProvider, AnnotationSource

All Known Subinterfaces:

MethodBasedRouteMatch<T,R>, MethodExecutionHandle<T,R>, UnsafeExecutionHandle<T,R>, UriRouteMatch<T,R>

public interface ExecutionHandle<T,R>
extends AnnotationMetadataDelegate

Represents a handle to an executable object. Differs from Executable in that the first argument to invoke(Object...) is not the object instead the object is typically held within the handle itself.

Executable handles are also applicable to constructors and static methods

Since:

1.0
